Cleistogamous flowers:
AInsect-pollinated
BWind-pollinated
CNever open; obligate self-pollination — bud-form structure
DOpen flowers
Answer & Solution
Correct answer: C. Never open; obligate self-pollination — bud-form structure
Cleistogamy: flowers that never open. Self-pollination assured. Found in some grasses (Oxalis, Commelina, Viola, Commelina benghalensis). Often produced in addition to chasmogamous (normal open) flowers — bet-hedging strategy. Drawback: no cross-fertilization → no genetic variation.
